SPARK-2634: Change MapOutputTrackerWorker.mapStatuses to ConcurrentHashMap
MapOutputTrackerWorker.mapStatuses is used concurrently, it should be
thread-safe. This bug has already been fixed in #1328. Nevertheless,
considering #1328 won't be merged soon, I send this trivial fix and hope this
issue can be solved soon.
